CAD (Computer aided design) and CAM (computer aided manufacturing) is a term that refers to computer systems that are used to both design and manufacture products. CAD is a combination of hardware and software that enables the engineers and the architects to design everything. The models which were created by CAD, appears on a computer monitor as a three-dimensional representation of a part or a system of parts, which can be readily altered by changing relevant parameters. CAD Technology is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing with less turnaround time. It is used in many fields like electronics, mechanics, computer, etc.

Python-Programming-Language

CAD software can be used to create curves and figures in two-dimensional (2D) drawings; or curves, surfaces, and solids in three-dimensional (3D) models. CAD / CAM software is most often used for product development, machine-tooling, and manufacturing. The 3D CAD and CAM represents 3-dimensional objects on a computer. 3D Wireframe, 3D dumb or 3D parametric are the different types of 3D CAD, which is designed for specific purposes.

Python:

Python is one of the highly technology oriented language, developed this application with remarkable features. It allows the users to develop and integrate applications in a simple way. The Python Development team developed lots of frameworks such as Django, TurboGears, Pylons, web.py, web2py, Grok, Zope2, ZODB, Durus, Bittorent, Pylatte, Tornado, Miro Community, Scrapy, Bobo, CherryPy, PyWebLib, etc. The applications written in Python are Web Applications (Django, Pylons), Games (Eve Online – MMORPG), 3D CAD/CAM, Image Applications, Science and Education Applications, Software Development (Trac for Project Management), Object Databases (ZODB / Durus), Console Applications, Enterprise Applications, Network Programming (Bittorent), Mobile applications, Audio/Video Applications, System Administration Applications, Office Applications, etc.

How Python used in 3D CAD and CAM application:

Python supports a wide range of functionalities for 3D CAD & CAM application such as FreeCAD, Fandango, CAMVOX, HeeksCNC, AnyCAD, HeeksPython, PythonOCC, PythonCAD, Blender, Vintech RCAM, etc.

  • CAMVOX is a 3D CAM type and a project in C++ and Python, using constructive solid geometry for the design and a voxel space to calculate tool paths.
  • FreeCAD is an Open Source CAx RAD based on Open Cascade, Qt and Python. It runs on Windows, Mac OSX and Linux platforms. Some of the general features of FreeCAD is full macro recording & editing, Workbenches, fully customizable / scriptable graphical user interface, etc. It can able to run as a server and dynamically loadable Application extensions and it’s designed to be platform independent.
  • PythonCAD is a CAD package written in Python. The PythonCAD project aims to produce a scriptable, open-source, easy to use CAD package for Linux, the various flavors of BSD Unix, commercial Unix, and other platforms to which someone who is interested ports the program.
  • Blender is an open source 3D graphics application, which is available for all major operating systems under the GNU General Public License. It only uses Python as a scripting language. It can be used for modelling, UV unwrapping, texturing, rigging, water simulations, skinning, animating, rendering, particle and other simulations, non-linear editing, compositing, and creating interactive 3D applications.
  • PythonOCC is a 3D CAD/PLM development library for the Python programming language. It is built upon the OpenCASCADE 3D modeling kernel, the salomegeom and salomesmesh packages.

Python is packed with rich libraries and many add-on packages to tackle specific tasks. It helps in 3D CAD & CAM Development. Python integrated with 3D CAD & CAM Application in order to provide best services.
